A novel suture removal instrument, kit and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and / or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

A grill having a platen with a plurality of heating zones. Each heating zone has a heating unit. Thermal transfer between adjacent heat zones is limited by air gaps and insulation. The heater unit of each zone has a heater that is disposed to attain substantially uniform temperature of the platen for that zone before a temperature sensor senses a set temperature during either pre-heat or recovery modes.

An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450% greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

A method of calibrating an individual sensor whose output varies with at least one operating condition. A generic calibration curve is produced for the variation of the sensor reading with the at least one operating condition for the particular sensor type of the individual sensor. Calibration readings are then taken for the individual sensor at just a small number of discrete values for the at least one operating condition which fall within the full range of operating values for the at least one operating condition for which the sensor is to be calibrated. Using the calibration readings, the generic calibration curve is then scaled in order to fit the generic curve to the individual sensor.

The intermittent linear motor of this invention incorporates features which enhance the exhaust scavenging and cooling processes, as well as simplifying overall construction including a compression plenum below the piston where air displaced during a power stroke by the piston is immediately transferred through the combustion chamber allowing said compressed air to immediately begin scavenging exhaust gases as the piston is returned further displacing spent gases from the motor.

Problems such as thermal pole tip protrusion result from thermal mismatch between the alumina and pole material during the writing process. This, and similar problems due to inadequate heat dissipation, have been overcome by dividing the bottom shield into two pieces both of which sit on top of a non-magnetic heat sink. Heat generated by the coil during writing is transferred to the non-magnetic heat sink whence it gets transferred to the substrate. With this approach, the head not only benefits from less field disturbance due to the small shield but also improves heat dissipation from the additional heat sink
